有VPN的系统设置.我将可能基于VpnService类添加其他VPN服务.如我所见,有一个方法setConfigureIntent看起来与我需要的东西相似,但是我看不到任何用法示例.

public VpnService.Builder setConfigureIntent (PendingIntent intent)

Added in API level 14
Set the PendingIntent to an activity for users to configure the VPN connection. If it is not set, the button to configure will not be shown in system-managed dialogs.

VPN设置页面在这里：

,.

实际上,我只需要向系统VPN设置添加一个按钮,然后单击显示带有VPN特定设置的自定义对话框即可.

解决方法:

这是使用Java Reflection提出的@shoe rat的起点：

            }else if(vpnProfileMap.get(key).equals(boolean.class) && values.get(key)!=null){

        }

我没有时间测试它,但是可以肯定的是它将为您提供一个起点.我不确定访问此隐藏的API是否需要root用户访问权限.请记住,这可能会引发一些SecurityException或IllegalAccessException.
